My instrument cluster has power to the instrument cluster but everything works besides the gauges. The engine temperature gauge says that the engine is overheating but I have looked at my coolant levels, checked my oil and it seemed fine. I also had the vehicle idling for at least five minutes and everything was normal. Battery voltage gauge does not work. I have honestly have been working on trying to locate the problem for the last three weeks and have not figured it out. I checked my fuses, my connections, which were perfect, and also have had to pull the entire dash out at least six times and I am not exaggerating I literally have. Anyone know what I need to do? I am honestly not sure if there is no ground or any problem with my factory connections?

Hello,

It sounds like the cluster needs to be rebuilt, but to be sure lets check the wiring to the cluster using this guide and the cluster wiring diagrams below.

Is everything checks out remove the cluster to have it rebuilt. Here is a video that gives you the idea on what to do:
